Operating the Analyzer

–45
If the 4-20 mA Val Action parameter is set to “1”, the 4-20 mA signal will
output validation measurements and the appropriate relay (Val #1 Active or Val
#2 Active) will be activated. If the concentration measured does not fall within
the allowable limits during an automatic or semi-automatic validation (see
“Validation Allowance” on page 2-33), the Validation Fail Alarm relay will
activate. Once activated, the Validation Fail Alarm must be manually
canceled (see “Cancel Val Alarms” on page 2-19). Initiating a new
automatic, semi-automatic or manual validation will clear the Validation Fail
Alarm so that the new validation can determine its state.
Calibrating the Analyzer
Calibrating the analyzer is typically not required under normal circumstances.
SpectraSensors calibrates each analyzer to a National Institute of Standards
and Technology (NIST) traceable standard before shipping the unit to the end
user. Because SpectraSensors analyzers use a non-contact form of
measurement, they are relatively insensitive to contamination, are quite
rugged and virtually maintenance free ensuring years of reliable service.
Switching Stream Compositions
Some analyzers may be configured with dual stream compositions. To switch
between the two calibration methods, use the analyzer keypad to change the
system programming. Refer to the following steps.
TomeasureStream1
1. From the analyzer keypad, press the # key followed by the 2 key to
enter the Set Parameter Mode (Mode 2).
2. Enter the password (1688).
3. Scroll through the parameters until the parameter, “Background to
Use,” displays.
4. Press 0 (Prcs) and the ENTER key.
5. Press the # key followed by the 1 key to begin measurement.
SpectraSensors recommends validating the analyzer using only
the analyte mixed in the validation gas specified on the analyzer
calibration report. A bottle of test gas with a certified
concentration representing 50% of full scale (for single validation
systems) or bottles representing 20% and 80% of full scale (for
dual validation systems) are recommended.
When procuring a gas standard, make sure the background gas is
that specified or a mix that closely resembles the contents of the
process stream and have the gas standard certified to better than
the specified precision of the analyzer, if possible.
